ResumoReplacement of the first metatarsophalangeal (MTP) joint remains critical because of complex biomechanical conditions and implant fixation. After a 3-year follow-up, most patients who experienced an MTP joint replacement were extremely satisfied with the outcome. Plantar pressure distribution revealed a marked improvement. Nevertheless, recovery of MTP dorsiflexion was limited and joint stability worsened. Radiologically, one-third of the prostheses showed radiolucent lines as a sign of implant loosening. MTP replacement offers distinct advantages in the treatment of end-stage hallux rigidus, but requires further research on implant design and osseous fixation.
